A large twice-line-frequency light flicker is a problem for a light-emitting-diode (LED) lamp driven by a single-stage power-factor-correction (PFC) circuit. This paper proposes a driving circuit for solving this problem. Furthermore, possible factors that influence the light flicker of a single-stage PFC driven LED lamp are analyzed. The theoretical analysis results are verified by using both simulations and experiments.
